TUBULAR LAMP.

SPECIFICATION forming part of Iletters Patent No. 269,431, dated December Application filed August 7, 1882. (No model.)

To all whom 225 may concern:

Be it known thatI, JOHN KRUMMENAUER. of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Tubular Lamps, of which the following is a full,clear,and exact descripllOh, reference being bad to the accompanying drawing, and to the lettersof reference marked thereon.

My invention relates especially to lamps for outdoor use constructed upon the tubular principle, and has for its object the production of a device in which the conduits for fresh air 'to the burners are direct, the flow thereof being regulated in such a manner as'to prevent cutting down of the flame when the lamp is exposed in the wind. 1 also provide means for disconnecting the upper and lower portions of the structure for the purpose of packing for shipment, &c., and for reaching the interior of the air-tubes; and my invention involves certain novel and useful combinations or arrangements of parts and the peculiarities of construction and operation, all of which will be hereinafterfirst fullydescribed,and then pointe d out in the claims.

The drawing presented herewith shows a vertical central section of a lamp embodying my invention.

Like letters of reference indicate correspond in g parts. As heretofore constructed, lamps for out-- door use made upon the tubular principle have been so arranged that when exposed to a sevcre draft the flame would be out down in such,

a manner as to atford verylittlelight; but bymy improved construction this ditticulty is over coine,and a steady,uniform flame is obtained. A are the feed air-tubes, through which the air to support combustion is supplied to the burner.

B is the globe or chimney of the lamp. U is a supporting-post. A is an air-chamber located at the lower extremityof tubes A, a cavity, 0, being formed therein for the reception of the supportingpost. Heretot'ore the cavity and post have extended upward across the tubes to such a distance as in a measure to interrupt the flow of air therefrom. In my construction this difficulty is overcome by running chamber A farther below the tubes.

A is a collar placed upon the air-chamber A, adapted and arranged to engage with and support the removable oil-pot D. The bottom of said oil-pot may have a ring or depression,

(I, therein, arranged to form a tight connection with the collar upon the air-chamber when placed thereon. As heretofore constructed, the oil-pot in lamps of this class has been in- 630 closed or suspended in a surrounding jacket, requiring the consumption of much time and labor in its construction, the space between the oil-pot and the jacket constituting the conduit for the fresh air to the burner. In such a form the oil-pot holds buta limited supply of fuel, and must be frequently filled. As constructed by me, the top D of the oil-pot extends entirely across the same from side to side, the outer jacket being dispensed with. The air is conducted from chamber A through tubes A to the burners. By this means I greatlylreduce the cost of constructing the oil-pot, and provide storage-space for double the quantity of oil held by the oldtstyle. Another advantage gained is to provide a direct passage for the air to the burner.

D is a plate fitting over the oil'pot, leaving an air-space thereabove and forming a seat for the cone E. E is a burner of any approved style.

W is a filler through which oil may be supplied to the oil-pot, and w is a partition extending downward within the oil-pot, from the top thereof nearly to the bottom, leaving only sutfioient space for the passage of the oil there under. For convenience in packing the lamp for shipment and for reaching the interior of tubes A, said tubes are cut or dividedat a, anda section of tubing, to, is secured within the 0 lower portion ofA,extendingupward and forming a substantially tight joint between the parts when slipped together. v a is a catch holding the parts in place when united for use.

In packing the lamp the upper and lower portions may be disconnected, and by removing the globe the whole device may be packed in a much smaller space than heretofore has been necessary. It often occurs that during the summer season, when the lamps are little used, wasps or other insects build their nests within the tubes; but when arranged as above described the two parts may be disconnected, and by means of a wire -or other suitable instrument the obstruction may be easily removed. a

Near the top of globe or chimney B is located a plate, F. Mounted upon plate F is a ring or collar, L, fitting around the top of the globe and extending some distance thereabove. The upper edge of said collar is provided with a deflecting plate or surface, 1. Supported in close proximity thereabove is an annular defleeting-plate, l, the whole being surmounted by a cap or plate, 1 and the parts held together by a number of metal strips, 0, or in any other preferred manner. Opposite the extremity or mouth of each tube A col ar L is perforated or cut through. Surrounding collar L, and affixed a short distance therefrom upon plate F, is a second collar, L forming, with L, an annular chamber, open at top, wherein are perforations opposite the openings into the air-tubes. The upper edge of L is provided witha deflecting-plate, Z

By arranging the upper portion of the device as above described currents of air striking plates Z, l, and P will draw from the chimney or globe as well as drive a. portion of the fresh air down tubes A, as in the old construction, and without the added collar L with its deflecting-plate l, the flame will be cut down to such an extent as to greatly lessen the illuminating-power of the lamp. By my construction and arrangement part of the current is deflected into the air-space formed by collars L L and plate F, a portion thereof passing down the tubes to the burner, and the remainder through the perforations in L and out of the top ot' the device, whereby the current is balanced, and the flame is rendered steady and uniform.

Upon the interior of collar L,affixed thereto, are three or more springs,s, the upper extremities standing out from the collar when the chimney or globe B is pushed upward within the collar for the purpose of removing the oilpot,trimn.iing the wick, &c. The head I) therein presses the springs outward, and upon passing by their points'the globe is held'securely in position until pulled down, the shape of the bead being such as to throw the springs back against the collar, permitting the globe todrop into place upon the oil-pot.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In a lamp of the character herein specified, a removable oil-pot having a depression in the bottom adapted and arranged to engage with a supporting-collar, and one or more tubes forming a passage or passages from the airchamber below the oil-pot to the under side of the burner-cone above the oil-pot, substantially as shown and described.

2. In a lamp of the character herein specified, the combination, with tubes A and airchamber A, of the removable oil-pot D, having tubes or passages A therethrough, substantially as shown and described.

3. In a tubular lamp of the character herein specified, the combination, with the feed-air supply tubes or conduits, divided as set forth, of a thimble therein, and a spring-catch adapted and arranged to secure the parts in place, substantially as shown and described.

4. The combination, with collar L and globe B,of springs s,adapted and arranged to press against the globe below the bead therein and hold the globe suspended, as set forth.

5. The combination, with tubes A, of collar L bearing deflecting-plate 1 said collar being perforated, as set forth, and collar L, periorated in like manner at the mouth of each of the tubes, substantially as shown and descrlbed.

6. The combination, with perforated collars L and L of deflecting-plates Z, 1, l and Zr, and tubes A, the whole arranged to operate substantially as shown and described.

7. The combination, with collars L and L perforated as set forth, of deflecting-plates l, l, 1 and Z tubes A, leading to air-chamber A, and aremovable 0ilpot, I), provided with passages therethrough leading from the airchamber to the under side of the burner-cone, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.

JOHN KRUMMENAUER.
